Was Chessmaster pos versus Botvinik 30 sec\move

10...Bd7
 11.Qd2 Kh8 12.0-0-0 Bd7 13.Bf2

13...a6 14.Ne2! (Retreat for attack move 1 the knight is aming for g3 to suport
f5 but there are so manny attacking moves that this retreating move will not be
the number1 choise for a program simply because it doesn't threat something yet!
 But in the maintime it also slows down the posible counter attacks from black.

[14.Bh4 f6 15.exf6 Bxf6 16.f5!? Is not as clear;



14...Qb8 15.Be3 Threatens f5 Ng8
16.h4! (Looked kind of strange because the idea of Ng3 and f5 was at question
here  ..,f5 17.h5!
(The idea behind h4 becomes clear gxh5
18.gxf5 Rxf5 (exf5 mostlikely was better
 19.Ng3 Rf8 20.Nxh5 Bh6 21.Nh2! (An other retreating move to build up the attack
It will not be played quickly by a program because of the same reason as 13.Ne2)

 Qe8 22.Ng4 Qg6 23.Nhf6 Nce7 24.Bd3+- Line

And if you want to know what setting of chessmaster pos are
it is the default chessmaster
only selectivety is brought to 10 amd Material\pos to 20

Gambit Tiger might be an exception here I haven't checked it.
